摘要:

为了解决在实际施工活动中工程振动对馆藏石造像文物的潜在危胁,基于ABAQUS有限元分析,建立了青岛市博物馆4尊大型石造像的有限元模型。对石造像有限元模型基底施加实测施工振动,通过有限元逐步增量动力时程分析,结合石造像抗拉强度本构关系、长期振动监测,得到合理的石造像文物振动安全阈值。提出大型石造像文物的数值建模方法,开展了修缮材料水硬性石灰抗拉强度试验。结果表明:4尊石造像的脖颈处、足部为振动敏感区域,可采用有针对性的保护措施。右侧石佛造像因其体量及本构参数的不同,对工程振动最为敏感,建议工程振动安全阈值设为1.5 mm/s。

Abstract:

To address the possible influence to the four stone Buddha statues in the Qingdao Museum brought by construction activities,we use the Finite Element Analysis software,ABAQUS,to build the Finite Element models of these statues. Then we apply the measured vibration to the bases of the Finite Element models,and do incremental dynamic analysis. Referring to the tensile-strength constitutive relations of the statues and the results from their long-term vibration monitoring,we propose vibration safety threshold for these stone statues. In addition,we put forward a numerical modeling method for large-scale stone statues,and carry out a tensile-strength test of hydraulic lime,a kind of restoration material. The results indicate that the neck and the feet of the stone Buddha statues are vulnerable to vibration,and need special protective measures. The Buddha statue on the right side is most sensitive to engineering vibration due to its unique volume and special constitutive parameters. The recommended safety threshold of engineering vibration for this statue is 1.5 mm/s.
